"In time series modeling, a nonlinear autoregressive exogenous model (NARX) is a nonlinear autoregressive model which has exogenous inputs. This means that the model relates the current value of a time series to both: • past values of the same series; and • current and past values of the driving (exogenous) series — that is, of the externally determined series that influences the series of interest.
